I gone through a lot of hosting service providers and unfortunetly cannot find a single one that can be used without running nonfree programs, all of them require loading bulky obfuscated JavaScript apps.
I know of Codeberg Pages for static sites for example, but it is not suitable for any business or professional use.
You need Javascript to run things like remote consoles and metrics dashboards. I don’t think its something you can really avoid tbh.
Why do you want to avoid Javascript so badly in this case? If its a matter of trust, a VPS provider can do far more damage by just using your payment information or messing with your server directly.
Web remote console or live metrics are understandable. But requiring scripts to register or show a header is something I try to avoid. And not because of security or privacy but out of principle of simplicity and healthy web ecosystem.
